Coeur Drills Highest Grade Intercept Ever in the Southern Silver Zone at Silvertip - Seite 2

“Exploration at Silvertip in 2023 achieved a key priority of expanding the resource base immediately adjacent to the main Silvertip deposit and existing underground infrastructure,” said Mitchell J. Krebs, President and Chief Executive Officer. “Recent results continue to reinforce the high-grade nature, overall size, and prospectivity of this exploration project. This success continues to support the growing potential of Silvertip as an emerging tier one asset and future cornerstone for the Company, containing some of the highest grades of silver, zinc and lead of any global carbonate replacement deposit in addition to a potentially meaningful complement of critical minerals.”

Resource expansion activities and step-out drilling commenced in July 2023 with the goals of expanding the Southern Silver Zone (the largest chimney structure identified on the property so far) and infill drilling at Saddle Zone to incorporate it into year-end resource calculations. During the year, approximately 90,000 feet (28,000 meters) of drilling were completed over 92 holes. Drilling into the Saddle Zone produced consistent, massive sulphide manto intercepts demonstrating the continuity of this new mineralized horizon. (Figures 2 and 3). Assays are still pending from the Saddle Zone.

Geological interpretation from both drilling and underground mine development has led to a new understanding of the geometries of manto and chimney mineralization and is forming the basis for a new Silvertip geological model expected to be completed in early 2024.

Between 2018 and 2023, the Company has invested roughly $60 million in exploration at the high-grade Silvertip deposit, leading to a near tripling of the total resource as of year-end 2022. A resource update based on 2023 drilling is expected to be included in Coeur’s year-end 2023 mineral resource and reserve update and will include a maiden estimate for the Saddle Zone.

“Exploration continues to uncover grades and geological features that indicate Silvertip is on the periphery of a much larger mineralizing system,” said Aoife McGrath, Senior Vice President of Exploration. “The resource has nearly tripled in just six years and we firmly believe that we have merely scratched the surface. The significant resource growth so far validates the immense potential, but we believe that the most potent and lucrative part of the deposit is yet to be uncovered, promising an exciting phase of exploration and development that has the potential to elevate Silvertip into a world-class carbonate replacement mineralizing system.”
